On a system running 2.4.25 here I have:
$ ifconfig

The same TX & RX are shown for both interfaces.
I don't know whether the tools have changed much since those I'm using on this
box, but the difference *might* be that Grant's IPs are on the same subnet. I
*think* it's possible for the route (as in: `man route`) to configure packets
that come in on 1.2.3.2 to be replied to via 1.2.3.1.
You might set up a spare test box to see how current ifconfig displays packets,
comparing aliased addresses on the same and separate subnets.
Stroller.
